History
ColdFusion 8: Added this function.
Parameters
Parameter | Description |
fileobj | The file to close. |
Usage
Always close a file after opening it. When you use the FileOpen function to open a file, the file stream is opened and contents are read from or written to it. The FileClose function closes the stream. If you do not close a file, the stream remains open; in that case, the operating system can lock the file, which results in the file not being usable until the server is restarted.
Example
The following example checks to see if a file is still open and closes it.
<cfscript>
myfile = FileOpen("c:\my\custom\location\test1.txt", "read");
while(NOT FileIsEOF(myfile))
{
x = FileReadLine(myfile);
WriteOutput("#x# <br>");
}
</cfscript>
<!--- Additional code goes here. --->
<cfif #myfile.status# IS "open">
<cfoutput>The file #myfile.filepath# is #myfile.status#</cfoutput> <br>
<cfscript>
FileClose(myfile);
</cfscript>
</cfif>
